James Webb Discovers Earth 3.0 - It Might Already Be Occupied | Space Documentary

Описание: James Webb Discovers Earth 3.0 - It Might Already Be Occupied | Space Documentary

Dive into the mystery of Kepler-442b, a super-Earth in the constellation Lyra that many astronomers consider one of the best real candidates for an “Earth 3.0”. In this space documentary–style breakdown, we explore how the James Webb Space Telescope (JWST) and future observatories could study this potentially habitable exoplanet from 1,196 light-years away, reading its atmosphere for biosignatures and technosignatures that might reveal alien life. You’ll learn how Kepler first discovered this world, why its K-dwarf star, 112-day year, and position in the habitable zone make it so special, and what signs—like oxygen, methane, industrial gases, or even waste heat—we’d look for to tell if Kepler-442b is already occupied. If you’re into cosmology, exoplanets, JWST discoveries, and the search for intelligent extraterrestrial life, this video is your deep dive into one of the most promising worlds we’ve ever found.
